WATER-REGULATOR ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 388,954, datedSeptember 4, 3.888.

I Application tiled May 11, 188B. Serial No. 273,583. (No model.)

To til wtom/ it may concern:

Be it known that I, MARTIN CnnsALiA, a citizen ofthe UnitedStates,residing in the city and county of San Francisco,and State ofCalifornia, have invented certain new and useful Improvements inPressuie,Regulators for falter-Supply Pipes; and I do hereby declarethat the following is a i'nll, clear, and exact description of niy saidinvention, reference being had to the drawings that accompany and formpart of this specification.

This invention relates lo devices for reguloting the force or pressureof water in service-pipes; and it is an improvement on that regulator ordevice for the purpose which has been made the subject of a priorapplication for patent by nie, the saine having been filed in the PatentOffice on or about the 18th day of April, 1388, Serial No. 27l,08l.

The present improvement consists in the addition to and combination,with thc spi der7 or pressure-reducer in my prior device, of anadjustabledisk ot' suitable size to cover the reducer,and capable ofbeing set at greater or less distance in front ofthat part, and withacock or plug and its chamber; also, in certain construction andcombination ofpartsiorming an improved regulating device, all ashereinafter fully set forth.

The following description explains the na ture of these improvements andthe manner in which I proceed to construct, produce, and apply the same,the accompanying drawings being referred to by figures and letters.

Figure l is a vertical longitudinal section through the body and partsof the regulator, the same being placed in a service-pipe between themeter and the servicecock or faucet. 2 is a section taken horizontallythrough the center. Fig. 3 is a front view of the spider.

ing through this last-named part, is met and still more reduced invelocity by the disk. The spider is fixed in the service-pipe, the sameas in my former device; but the disk is adjustable toward and from theback of the spider to contract or enlarge the area of the passage. Thisadjustment is provided for by fixing the disk on aserew-threaded stem,Ax, and setting the same through a post or bearing in the body of thedevice, suitable nuts and washers being used to hohl the stem in place.In the present improved construction I combine all these parts with aplug or shutoff cock, so that the device in itself answers both for aregulator and a shut oiif cock. This dispenses with the additional laborand tronble of inserting a plug or cock in the servicepipe in additionto the regulating device, as it reduces the cutting of the pipe and theadditional joints.

The body B is fitted with a plug, C, provided with a handle, C, andseated in the usual manner in the body. In the center ot' the way oropening, (32, through the plug is a web supporting a boss, D, in whichthe stern A of the disk-regulator is set. The hole through this boss isin line with the center of the spider, and the stem passing through itis held by nuts e c against longitudinal movement.

The width of the chamber BX is suitably' proportioned to allow the diskto swing around as the plug C is turned, so that although this part iscarried by the plug it does not interfere with the movement of the plug,and this last-named part can be turned in its seat when it is necessaryto shut off supply-water.

The chamber I3X is divided by the partitions b b into inlet and deliverysides, in the former of which the regulator operates, and the body B isprovided with an opening in the top closed by a screwthreaded part, B',for the purpose of allowing the plug and the regulating-disk to bewithdrawnvand replaced as oe casion may require to set the disk at thedesired distance from the fixed spider. The ends of the body arescrew-threaded or other wise formed for inserting and joining the endsof the service-pipe.

Having thus fully described my invention, In testimony that; I claim theforegoing [o what I claim, and desire to secure by Letters have hereuntoseb my hand andseal. Patent, is-
